泡桐是平原绿化的重要树种之一,采用埋根方法育苗,繁殖率低、成本高,因而影响这一树种的发展。1982年以来,我们连续二年采用泡桐留根茬上的萌蘖芽,进行嫩枝扦插试验获得成功,现介绍如下: 一、材料的采集 秋末春初对1年生泡桐苗平茬时,适当增大所封的土堆,在4月中下旬,每株泡桐苗茬可萌生4至6个嫩枝。嫩枝长至4—6片真叶后留下一个枝培养大苗,其余嫩枝自 Paulownia is one of the important species of plains greening, the use of buried root nursery, low reproduction rate, high cost, thus affecting the development of this species. Since 1982, we use two consecutive years of Paulownia stubble on the budding shoots, shoots cuttings test success, are described as follows: First, the material collected in the late autumn and early Spring Paulownia seedling stubble, the appropriate increase Large enclosed mound, in late April, each Paulownia stubble can sprout 4 to 6 shoots. The length of the shoots is about 4-6 leaves. After the leaves are left, one branch is left to cultivate the seedlings and the remaining shoots are self-contained
